|
||
|
|
<div><p>When you use Collection Services to collect performance data, you
|
||
|
|
control what data is collected and how often it is collected.</p>
|
||
|
|
<div class="section"><p>You can select from the collection profiles that are provided.
|
||
|
|
The <span class="uicontrol">Standard</span> profile corresponds to the settings for
|
||
|
|
system data in the <span class="keyword">i5/OS™</span> performance
|
||
|
|
monitor function that was provided by the <span class="cmdname">Start Performance Monitor
|
||
|
|
(STRPFRMON)</span> command in previous releases. The <span class="uicontrol">Standard
|
||
|
|
plus protocol</span> profile corresponds to the STRPFRMON command settings
|
||
|
|
for all data. Or you can select <span class="uicontrol">Custom</span> to create your
|
||
|
|
own customized profile. There are also several other profiles available, refer
|
||
|
|
to the online help for detailed descriptions. For your customized profile,
|
||
|
|
you can select from a list of available data categories, such as System CPU,
|
||
|
|
Local Response Time, Disk Storage, and IOPs (input/output processors).</p>
|
||
|
|
<p>For
|
||
|
|
each category of data that you collect, you can specify how often the data
|
||
|
|
will be collected. For many categories, you will want to select the default
|
||
|
|
collection interval, which you can set from predefined settings between 15
|
||
|
|
seconds and 60 minutes. (The recommended setting is 15 minutes.)</p>
|
||
|
|
<div class="note"><span class="notetitle">Note:</span> When
|
||
|
|
the default value is set to any specified time, all categories except those
|
||
|
|
categories with explicit time intervals, such as, disk storage, input/output
|
||
|
|
processors, and communications-related categories, use the specified time.</div>
|
||
|
|
<p>The
|
||
|
|
collected data is stored in a management collection object (type *MGTCOL)
|
||
|
|
called a collection. To prevent these management collection objects from becoming
|
||
|
|
too large, the collection must be cycled at regular intervals. Cycling a collection
|
||
|
|
means to create a new collection object and begin storing data in it at the
|
||
|
|
same time data collection stops in the original collection object. You can
|
||
|
|
specify any interval from one hour to 24 hours, depending on how you plan
|
||
|
|
to use the data.</p>
|
||
|
|
<p>To customize Collection Services on a system, follow
|
||
|
|
these steps:</p>
|
||
|
|
</div>
|
||
|
|
<ol><li><span>In <span class="keyword">iSeries™ Navigator</span>,
|
||
|
|
select either an endpoint system under <span class="uicontrol">Management Central</span> or
|
||
|
|
a system to which you have a direct connection under <span class="uicontrol">My Connections</span> (or
|
||
|
|
your active environment).</span></li>
|
||
|
|
<li><span>Expand <span class="uicontrol">Configuration and Service</span>.</span></li>
|
||
|
|
<li><span>Right-click <span class="uicontrol">Collection Services</span> and select <span class="uicontrol">Properties</span>.</span></li>
|
||
|
|
<li><span>On the <span class="uicontrol">General</span> page, you may want to specify
|
||
|
|
a retention period longer than the default of 1 day. Collection Services may
|
||
|
|
delete management collection objects and the data they contain from the system
|
||
|
|
at any time after the retention period has expired. When the management collection
|
||
|
|
object is created, an expiration date is assigned to it. Even if you move
|
||
|
|
the collection object to another library, Collection Services will delete
|
||
|
|
the object after it expires. You can specify <span class="uicontrol">Permanent</span> if
|
||
|
|
you do not want Collection Services to assign an expiration date to new collection
|
||
|
|
objects. You will then have to delete these collection objects manually. To
|
||
|
|
view the Graph History window, you must specify a Collection retention period
|
||
|
|
of either Graph or Summary. When you specify these options, you can take advantage
|
||
|
|
of the historical reporting capabilities, which allow you to do metric comparisons
|
||
|
|
for multiple systems over extended periods of time. You can also specify the
|
||
|
|
path of the location where you want to store your collections, how often you
|
||
|
|
want to cycle collections, and the default collection interval. You can select
|
||
|
|
to create database files automatically during collection.</span></li>
|
||

<li><span>Click the <span class="uicontrol">Data to Collect</span> tab.</span></li>
|
||
|
|
<li><span>For <span class="uicontrol">Collection profile to use</span>, select <span class="uicontrol">Custom</span>.
|
||
|
|
You can specify the collection interval for each category you select for your
|
||
|
|
customized list.</span></li>
